Abatement LLC, Eagle Office Box 5110, Eagle, Colorado 81631. Site: 610 South West End Street unit F202 Aspen CO 81611 - The Gant Asbestos air Clearance conducted after abatement of identified asbestos containing wall and ceiling texture material. Abatement was conducted prior to planned renovation and repair within the Unit containment area. Task 1 -Field Work: Project Scope of Work Conducted during Air Monitoring: 1. Contractor conducted abatement according to applicable Colorado Regulation 8, EPA and OSHA regulations for an abatement within a containment system in: OSHA: required containment system, and negative pressure system. 2. Completion of final inspections. 2.0 SAMPLE COLLECTION METHODS EDT ACM LLC used NIOSH method 7400, 40 CFR 763 AHERA and OSHA 29CFR 9010 methodology during activities to support abatement activity: 4-1 RECEIVED 04/11/2018 ASPEN BUILDING DEPARTMENT ENVIRONMENTAL AIR SAMPLES ADJACENT TO THE WORK AREA: Environmental sampling was conducted post abatement activity. The air samples were collected on 25 mm cassettes with 0.8u filters and analyzed by R2 Analytical according to NIOSH method 7400. All environmental samples were less than or equal to 0.01 f/cc (fibers per cubic centimeter of air sampled). No fiber concentrations were observed in excess of the OSHA 29CFR 9010 or the CDPHE Allowable Asbestos Level (MAAL). FINAL AIR SAMPLES: Clearance air sampling was conducted according to Colorado Regulation 8. All of the clearance samples collected within the work area were less than 0.01 F/CC, (fibers per Cubic Centimeter. No concentrations were observed in excess of the Maximum Allowable Asbestos Level (MAAL). 3.0 CONCLUSIONS Based on observations during the site visit, and the laboratory analytical results, EDT LLC ACM concludes the following: All Environmental and Final work Area or Clearance Air samples collected outside and inside the regulated work area clearance criteria indicated; fiber concentrations less than or equal to 0.01 f/cc (fibers per cubic centimeter of air sampled). No fiber concentrations were observed in excess of the Maximum Allowable Asbestos Level (MAAL)per CDPHE. 4-2 RECEIVED 04/11/2018 ASPEN BUILDING DEPARTMENT Based on sampling and analysis results attached, no further action is recommended or required for this phase of the project for the impacted areas. As additional abatement items are addressed environmental and clearance air monitoring should be performed according to Colorado and EPA Regulations.
